To all whom it may concern: l Be it known that we, JAMES W. SEE and CORLISS SEE, citizens of the UnitedStat-carebeing intended for use in connection with* noisy celebrations.

This invention willzbe readily understood from the following description taken in con-f nection with the accompanying drawings, in whichv o Figure 1 is a side elevation of aA machine exemplifying our invention; Fig. 2, a vertical longitudinal section of the samein the plane of the transverse centerof the machine;

Fig. 3, a plan with the hammer and the channel-cover omitted; Fig.`4:, a rear end elevation; Fig. 5, a vertical transverse section in the plane of line a; Fig. 6, a vertical transverse section in the plane of line b, and Fig. 7 a vertical transverse section of one of the resonating-braces in the line of c.

In the drawings,1 indicates an anvil against which the fulminate is to be exploded; 2,"the

. the firing-pin, being a reduced projectionl striking agent which is to explode it, the same being illustrated in the present instance as a'hammer 3, an explosion-chamber formed between the anvil and the striking agent; 4,

from the face of the iring agent, adapted to strike against the reduced central face of the anvil; 5, the arm ofthe hammer; 6, the main frame, carrying the anvil; 7, a pivot mounted in the main frame for the hammer-arm; 8, a stop-pin carried by the main frame in Vany selective one of the series of holes over the hammer-arm; 9, a spring carried by the hammer-arm and adapted, as the hammer rises, to make 'contact with the stop-pin; 10, a gutter extending lengthwiseV .in the frame and having a width sufficient to freely pass the tape of fulminates; 11, the floor of this gutter, its upper surface being at substantially the same level asthe surface of the anvil;

l v12, a roof-plate disposed removably over the `forward portion of the gutter, its forward end extending well in toward the center of the anvil; 13, a pinfor removably securing the roof-plate in position on the frame; 14, a narrow rearward extension of the anvil from the center of the anvil toward the forward end of the gutter, the other portions of the general upper face of the anvil sloping downwardly from its center; 15, a central slot in the forward end of the ioor of the gutter of less width than the tape to be dealt with, so that the iioor will still furnish a support for the tape at each side of the slot; 16, a plate sliding horizontaily in guides at the rear end of the frame; 17, a thin flat feed-pawl carried by this sliding plate and extending under the floor of the gutter and having its forward end projectingup through the slot therein and yieldingly pressing up against the roofplate; 18, a spring tending to urge this feedpawl forwardly, the' drawings showing the pawl inV its rearward position, its forward motion being limited by contact of a-portion of the sliding' plate with the rear end of the floor of the gutter, the stroke of the pawl corresponding with the distance between the fulminating-Wafersupon the tape; 19,a springstopped pawl carried by the frame, its forward end projecting up through the slot in the oor of the gutter and Vupwardly against the, roof-plate'to the rear of the active end of the feed-pawl; 20, an upward projection from sliding plate 16; 21, a toe projecting from the hammer-arm and engaging the inner face of projection 20 and adapted when the hammer is down upon the anvil to carry and hold the feed-pawl at its rearward limit of stroke; 22, a port through the projection 20 to permit the passage of the tape of fulminate endwise into the gutter; 23, a pin carried by the vframe to be employed, when desired, in sustaining the coil of the tape, and 24., thin hollow resonators connected with the anvil and preferably taking the form of braces integrally projecting sidewise therefrom.

The end of the tape of spaced fulminates is passed through the port 22 and laid in the gutter 10 and over the` pawls, the wafer-like projections of the fulminates being downward, the feed-pawl catching to the rear of roo vplate may, if desired, be removed.

the second fulminate of the tape. In thus threading the tape into the machine the cover- The greater length of the tape may extend out onto the ground or it may be coiled and supported on the pin 23. The hammer is then raised, thus permitting the spring 18 to feed the tape forward one space, which brings the first fulminate over the center of the anvil. The hammer is then allowed ,to fall, whereupon the firing-pin strikes the fulminate and explodes it. The reaction of the explosion thrusts the hammer up and causes another fulminate to feed forward, which in turn will be exploded by the falling hammer, and so on and on till the tape is exhausted, the machine being automatic after the first fall of the hammer. As the object is to make as much noise as possible, the sound due directly to the explosion may well be reinforced by resonators around the machine, and for this purpose the resonating-braces are employed and the general frame is made light and hollow.

The general body of the anvil is given a conical form in order that it may readily shed lhe residuum of the explosions. This conical form is also peculiarly beneficial in connection with the cupped hammer-face in producing piston-like action between the hammer and anvil. The an vil extension 14 serves in building up this shedding-surface in the direct path of the tape, and the notch seen in the cup-rim of the hammer provides for the reception of this extension as well as for the narrow forward end of the roof-plate, so that the tape is pretty well housed in till it gets very close to the striking-point of the anvil.

The period between detonations will depend upon the force of the explosives, upon the weight of the hammer, and upon the length of the arm. The hammer-spring 9 serves in giving a cushioning arrest to the upstroke of the hammer and in quickening the reversal of the hammer motion, and by varying the position of the stop-pin 8 the length of hammer-stroke may be varied, thus altering the length of period between detonations.

We claim as our inventionl.A In a detonating-machine, the combination, substantially as set forth, of an anvil forming one wall of an explosion-chamber, a striking agent coperating therewith and forming the opposite wall of the explosionchamber whereby the force of the explosion acts directly on said walls and tends to separate them, means for automatically restoring contact between the anvil and striking agent after their separation, a feed device for carrying explosives successively between the anvil and striking agent, and/connections between the striking agent and feed device to cause the mot-ion of separation of the striking agent from the anvil to bring about an impulse of the feed device.
